Seek time  
Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using  
drive diagnostics. The specifications below are defined as follows:  
• Track-to-track seek time is an average of all possible single-track seeks in both directions.  
• Average seek time is a true statistical random average of at least 5,000 measurements of seeks between  
random tracks, less overhead.

Note. These drives are designed to consistently meet the seek times represented in this manual. Physical seeks,  
regardless of mode (such as track-to-track and average), are expected to meet or exceed the noted values.  
However, due to the manner in which these drives are formatted, benchmark tests that include command  
overhead or measure logical seeks may produce results that vary from these specifications.

Power specifications  
The drive receives DC power (+5V) through the interface connector.  
2.9.1 Power consumption  
Power requirements for the drives are listed in the Table 2 on page 8. Typical power measurements are based  
on an average of drives tested, under nominal conditions, using 5.0V input voltage at 25°C ambient tempera-  
ture.  
• Spinup power  
Spinup power is measured fromthe time ofpower-onto thetimethat the drive spindle reaches operating speed.  
• Seek mode  
During seek mode, the read/write actuator arm moves toward a specific position on the disc surface and does  
not execute a read or write operation. Servo electronics are active. Seek mode power is measured based on  
three random seek operations every 100 msecs. This mode is not typical.  
Read/write power and current  
Read/write power is measured with the heads on track, based on three 63 sector read or write operations  
every 100 msecs.  
• Operating power and current  
Operating power is measured using 40 percent random seeks, 40 percent read/write mode (1 write for each  
10 reads) and 20 percent drive idle mode.  
• Idle mode power  
Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in  
a random track location.  
• Standby mode  
During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/  
write electronics are in power-down mode.

Conducted noise  
Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on  
the +5 volt line.  
Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave  
injected noise at up to 10 MHz.  
Note. Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write  
current.

• Active mode  
The drive is in Active mode during the read/write and seek operations.  
• Idle mode  
The buffer remains enabled, and the drive accepts all commands and returns to Active mode any time disc  
access is necessary.  
• Standby mode  
The drive enters Standby mode when the host sends a Standby Immediate command. If the host has set the  
standby timer, the drive can also enter Standby mode automatically after the drive has been inactive for a  
specifiable length of time. The standby timer delay is established using a Standby or Idle command. In Standby  
mode, the drive buffer is in Self Refresh Low Power mode, the heads are parked and the spindle is at rest.  
The drive accepts all commands and returns to Active mode any time disc access is necessary.  
• Sleep mode  
The drive enters Sleep mode after receiving a Sleep command from the host. In Sleep mode, the drive buffer  
is in Self Refresh Low Power mode, the heads are parked and the spindle is at rest. The drive leaves Sleep  
mode after it receives a Hard Reset or Soft Reset from the host. After receiving a reset, the drive exits Sleep  
mode and enters Standby mode with all current translation parameters intact.  
• Idle and Standby timers  
Each time the drive performs an Active function (read, write or seek), the standby timer is reinitialized and  
begins counting down from its specified delay times to zero. If the standby timer reaches zero before any drive  
activity is required, the drive makes a transition to Standby mode. In both Idle and Standby mode, the drive  
accepts all commands and returns to Active mode when disc access is necessary.

Acoustics  
Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All mea-  
surements are consistent with ISO document 7779. Sound power measurements are taken under essentially  
free-field conditions over a reflecting plane. For all tests, the drive is oriented with the cover facing upward.  
Note. For seek mode tests, the drive is placed in seek mode only. The number of seeks per second is defined  
by the following equation:  
(Number of seeks per second = 0.4 / (average latency + average access time)

FCC verification  
These drives are intended to be contained solely within a personal computer or similar enclosure (not attached  
as an external device). As such, each drive is considered to be a subassembly even when it is individually mar-  
keted to the customer. As a subassembly, no Federal Communications Commission verification or certification  
of the device is required.  
Seagate Technology LLC has tested this device in enclosures as described above to ensure that the total  
assembly (enclosure, disc drive, motherboard, power supply, etc.) does comply with the limits for a Class B  
computing device, pursuant to Subpart J, Part 15 of the FCC rules. Operation with noncertified assemblies is  
likely to result in interference to radio and television reception.  
Radio and television interference. This equipment generates and uses radio frequency energy and if not  
installed and used in strict accordance with the manufacturer’s instructions, may cause interference to radio  
and television reception.  
This equipment is designed to provide reasonable protection against such interference in a residential installa-  
tion. However, there is no guarantee that interference will not occur in a particular installation. If this equipment  
does cause interference to radio or television, which can be determined by turning the equipment on and off,  
you are encouraged to try one or more of the following corrective measures:  
• Reorient the receiving antenna.  
• Move the device to one side or the other of the radio or TV.  
• Move the device farther away from the radio or TV.  
• Plug the computer into a different outlet so that the receiver and computer are on different branch outlets.

Environmental protection  
Seagate designs its products to meet environmental protection requirements worldwide, including regulations  
restricting certain chemical substances.  
2.15.1  
European Union Restriction of Hazardous Substances (RoHS)  
The European Union Restriction of Hazardous Substances (RoHS) Directive restricts the presence of chemical  
substances, including Lead (Pb), in electronic products effective July 2006.  
A number of parts and materials in Seagate products are procured from external suppliers. We rely on the rep-  
resentations of our suppliers regarding the presence of RoHS substances in these parts and materials. Our  
supplier contracts require compliance with our chemical substance restrictions, and our suppliers document  
their compliance with our requirements by providing material content declarations for all parts and materials for  
the disc drives documented in this publication. Current supplier declarations include disclosure of the inclusion  
of any RoHS-regulated substance in such parts or materials.  
Seagate also has internal systems in place to ensure ongoing compliance with the RoHS Directive and all laws  
and regulations which restrict chemical content in electronic products. These systems include standard operat-  
ing procedures that ensure that restricted substances are not utilized in our manufacturing operations, labora-  
tory analytical validation testing, and an internal auditing process to ensure that all standard operating  
procedures are complied with.  
2.15.2  
2.16.2  
China Restriction of Hazardous Substances (RoHS) Directive  
This product has an Environmental Protection Use Period (EPUP) of 20 years. The following  
table contains information mandated by China's "Marking Requirements for Control of Pollution  
Caused by Electronic Information Products" Standard.

Configuring and mounting the drive  
This section contains the specifications and instructions for configuring and mounting the drive.  
3.1  
Handling and static discharge precautions  
After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic dis-  
charge (ESD) hazards. Observe the following standard handling and static-discharge precautions:  
• Keep the drive in the electrostatic discharge (ESD) bag until you are ready for installation to limit the drive’s  
exposure to ESD.  
• Before handling the drive, put on a grounded wrist strap, or ground yourself frequently by touching the metal  
chassis of a computer that is plugged into a grounded outlet. Wear a grounded wrist strap throughout the entire  
installation procedure.  
• Handle the drive only by its edges or frame.  
• The drive is fragile—handle it with care. Do not press down on the drive top cover.  
• Always rest the drive on a padded, antistatic surface until you mount it in the computer.  
• Do not touch the connector pins or the printed circuit board.  
• Do not remove the factory-installed labels from the drive or cover them with additional labels. Removal voids  
the warranty. Some factory-installed labels contain information needed to service the drive. Other labels are  
used to seal out dirt and contamination.  
3.2  
Jumper settings  
3.2.1  
Master/slave configuration  
Use the options jumper block shown in Figure 3 to configure the drive for operation. This jumper block is the 4-  
pin header adjacent to pins 1 and 2 of the I/O signal pins. For additional information about using the Cable  
select option, see section 3.2.2.  
The “Master or single drive” option is the factory default setting.  
Drive is master (or single drive)  
Drive is slave

Figure 3. Jumper settings  
Momentus 7200.1 PATA Product Manual, Rev. C  
19  
 
                     
3.2.2  
Cable-select option  
Computers that use cable select determine the master and slave drives by selecting or deselecting pin 28,  
CSEL, on the interface bus. Master and slave drives are determined by their physical position on the cable. To  
enable cable select, set a jumper as shown in Figure 3. Refer to your computer manual to determine whether  
your computer supports this option.  
3.3  
Drive mounting  
You can mount the drive using four screws in the side-mounting holes or four screws in the bottom-mounting  
holes. See Figure 4 for drive mounting dimensions. Follow these important mounting precautions when mount-  
ing the drive:  
• Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling.  
• Use only M3 UNC mounting screws.  
• Do not overtighten the mounting screws (maximum torque: 4.0 inch-lb).  
• Four (4) threads (0.080 inches) minimum screw engagement recommended.

ATA interface  
These drives use the industry-standard ATA task file interface that supports 16-bit data transfers. It supports  
ATA programmed input/output (PIO) modes 0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–5. The  
drive also supports the use of the IORDY signal to provide reliable high-speed data transfers.  
For detailed information about the ATA interface, refer to the draft of AT Attachment with Packet Interface  
Extension (ATA/ATAPI-6), NCITS T13 1410D, subsequently referred to as the Draft ATA-6 Standard.

Set Features command  
This command controls the implementation of various features that the drive supports. When the drive receives  
this command, it sets BSY, checks the contents of the Features register, clears BSY and generates an inter-  
rupt. If the value in the register does not represent a feature that the drive supports, the command is aborted.  
Power-on default has the read look-ahead and write caching features enabled. The acceptable values for the  
Features register are defined as follows:
